Testosterone is the primary anabolic hormone in men that plays an essential role in controlling muscle growth. In addition, increased testosterone enhances sexual interest, erectile function, mood, and bone density. No wonder so many products are marketed to naturally enhance testosterone. Many companies claim to have the latest, greatest testosterone booster, but none have a shred of scientific evidence to support the inflated hype.

Conducted by a team of doctors, in a medical college and hospital, a randomized, placebo-controlled, double blind product specific clinical trial was conducted to evaluate the testosterone-boosting effectiveness AndroTest in healthy adult men. Subjects in this clinical study were aged 35 to 55 years and were free from any medical problems that would confound testosterone levels. A total of 31 subjects completed the study; 16 received AndroTest and 15 the placebo. Statistical tests indicated a clearly significant increase in the AndroTest group compared to placebo for both free testosterone and total testosterone. Changes were seen as early as two weeks. AndroTest caused statistically significant increases in free testosterone levels, averaging 59.75% over baseline, and statistically significant increases in total testosterone levels, averaging 59.88%. These results represent actual increases over baseline (as opposed to figures which are compared to placebo), which makes these numbers truly unprecedented. Equally impressive is the fact that the increased testosterone levels after 2 weeks were maintained throughout the duration of the study. This finding is particularly noteworthy since sustained increases in testosterone are the key to really enhancing muscle growth. This is one of the first studies to look at this vitally important parameter.

I have to say, in all of my years as a researcher I truly have never seen more compelling evidence of the efficacy of a testosterone booster. The subjects receiving the placebo experienced decreases, or non-significant changes in free and total testosterone. These responses demonstrate the consistency and reliability of the testosterone-boosting properties of AndroTest.

Importantly, there were no side effects associated with supplementation. Blood cholesterol levels were not altered and all other clinical chemistries remained unchanged. It's very easy to get excited about these results because there is simply no other natural way to get this type of significant increase in resting testosterone levels.

It appears AndroTest is the real deal. If combined with a healthy diet and regular weight training, the predicted effects on muscle growth are clearly encouraging, to say the least. ProSource is recognized throughout the industry for providing the highest quality scientifically tested products, and this study proves AndroTest more than lives up to those high standards.
